請教一個英語句子如下：
MESBIC's are the result of the belief that providing established firms with easier access to relevant management techniques and more job-specific experience,as well as substantial amounts of capital,gives those firms a greater opportunity to develop sound business foundations than does simply making general management experience and small amounts of capital available.實在不知道為什么句子中g(shù)ives 做那個主語的謂語,還有,句首有個are,這樣算不算是謂語重復(fù).
